The age of Aquarius is dawning this summer at the Hollywood Bowl’s 2014 Summer Series with an all-star cast! The previously announced production of Hair will be led by Frozen star Kristen Bell as Sheila and Hunter Parrish as Claude, with Glee’s Amber Riley and Jenna Ushkowitz as Dionne and Jeanie, respectively. Joining them will be Beverly D’Angelo as Mom. Further casting will be announced at a later date. The Adam Shankman-helmed production will run August 1 through August 3.

Prior to singing about snowmen in Frozen, Bell appeared on Broadway in The Crucible and The Adventures of Tom Sawyer, as well as off-Broadway’s Reefer Madness. Her additional screen credits include Veronica Mars and Forgetting Sarah Marshall. Parrish, who starred in the TV series Weeds, made his Broadway debut as Melchior in Spring Awakening, and went on to star in the revival of Godspell. In addition to Glee, Riley (who recently won Season 17 of Dancing with the Stars) and Ushkowitz have appeared on the New York stage in Cotton Club Parade and Spring Awakening, respectively.

Hair follows a group of free-spirited youths who passionately preach a lifestyle of peace, love, freedom and happiness in a society that they see suffering from intolerance and brutality during the Vietnam War. The musical features such memorable numbers as “Let the Sun Shine In,” Aquarius” and “Good Morning Starshine.”
